Some bacteria live in hot springs. Their cells contain enzymes that function best at temperatures of 70 °C or higher. At the temperature of 50 °C, how will the enzymes in these bacterial cells most likely be affected?

The enzymes will not increase the rate of reactions as much as they would at 70 °C.

The enzymes will be destroyed by lysosomes

The enzymes will lose their bond structure and fall apart.

The enzymes will require less energy to function than at 70 °C.

The graph below shows how the activity of an enzyme changes over a range of pH values. Which of the following conclusions can be drawn from this graph?

The optimum pH of the enzyme is 6.6.

The optimum pH of the enzyme is 5.8

The enzyme’s activity continually increases as pH increases from 5.0 to 9.0

The enzyme’s activity is greater around pH of 8.0 than around pH of 5.0.

What will most likely happen if an appropriate enzyme is added to a chemical reaction?

The reaction rate will increase.

The equilibrium of the reaction will be maintained.

The reaction rate will decrease.

The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body. Which of the following describes the connection between these two statements?

Enzymes function best at a specific temperature.

The body needs to be warm to prevent hypothermia.

The body is kept relatively warm to prevent too much enzyme action.

There is no connection between the two statements.

As food travels through the digestive system, it is exposed to a variety of pH levels. The stomach has a pH of 2 due to the presence of hydrochloride acid (HCl), and the small intestine has a pH ranging from 7 to 9. HCl converts pepsinogen into pepsin, an enzyme that digests proteins in the stomach. Which of the following most likely happens to pepsin as it enters the small intestine?

It's shape changes to engulf large proteins.

It's activity increases to digest more proteins.

The graph shows how enzymes affect reactions in cells. Which statement best summarizes the information shown in the graph?

Enzyme decrease the activation energy of the reaction.

Enzymes increase the energy of the reactants.

Enzymes decrease the energy level of the products.

Enzymes reverse the direction of the reaction.

Enzymes need certain environmental conditions in order to function properly. What happens when enzymes are heated to a high temperature?

they change their amino acid sequence

What is the purpose of cellular respiration?

there is none; it's a waste of time

What is the correct equation for cellular respiration?

6O 2 + C 6 H 12 O 6 -> 6CO 2 + 6H 2 O + Energy

6O 2 + C 6 H 12 O 6 + Energy -> 6CO 2 + 6H 2 O

6CO 2 + 6H 2 O -> 6O 2 + C 6 H 12 O 6 + Energy

6CO 2 + 6H 2 O + Energy -> 6O 2 + C 6 H 12 O 6

Which of the following is the correct equation for PHOTOSYNTHESIS?

CO 2 + light + H 2 O --> O 2 + Sugar

CO 2 + sugar + H 2 O --> O 2 + light

O2 + light + H 2 O --> CO 2 + Sugar

CO 2 + O 2 + H 2 O --> Light+ Sugar

A product of photosynthesis and a reactant of cellular respiration

A product of photosynthesis and cellular respiration

A reactant of photosynthesis and cellular respiration

A reactant of photosynthesis and a product of cellular respiration

A form of energy the cell can use that is produced by cellular respiration

A kind of sugar produced in photosynthesis
